IMPROVEMENT IN OIL-CANS.

Specification forming part of Letters Patent No. 136,544, dated March 4,1873.

To all whom it may concern.'

Beit known that I, AARON RQUINBY, of the city ot' Newark, in the county'ol'lEsseX and btate of New Jersey, have invented an Improvement inOil-Gans, ot' which the following is a specitication:

This invention relates to oil-cans which are constructed or providedwith elastic bottoms that on external pressure, as by the thumb, beingapplied to them serve to eject oil from the body ot' the can through anozzle attached thereto. In such cans there is a liability ot the oil tospill orooze through the nozzle whenever the can is inverted orsuiiiciently inclined to give its nozzle dip, so that on the atmosphericpressure in the can being equal to that on the outside or at the mouthot' thel nozzle the oil is caused to iiow by gravity through and out otthe nozzle. My invention has for its object the remedying ot' thisdefect; and consists in a combination, with the elastic bottom andnozzle or outlet ot' the can, ot' a tubular stud attached to the bottom,and a sleeve attached to the nozzle and fitting over the said stud, thesaid stud and sleeve having openings in them, whereby they are made toserve as a valve that ei'ectually excludes escape through the nozzleexcepting when pressure is applied to the elastic bottom to eject theoil, when the valve is opened by the inward motion or deiection ot' theelastic bottom.

ln the accompanying drawing, which forms part ot' this specification,Figures l and 2 represent central longitudinal sections ot' an oilcanhaving my improvement applied, and showing the elastic bottom ordiaphragm ot' the can before it is sprung inward and after it has beenso adjusted to expel the oil. Fig. 3 is a longitudinal view of a modiedconstruction of the nozzle to that shown in Figs.' l and 2.

Similar letters of reference indicate corresponding parts.

In Figs. 1 and 2, A represents the body of the can; B, its nozzle; andi, its elastic bottom or diaphragm. The nozzle B has a tubularextension, b, arranged toproject some dista-nce down within the body A,and which may either be of the same piece with the nozzle or a separa-teattachment. This ltubular nozzle extension b has one or more sideopenings, c, in it at any desired point or points between its inner endand the top ot' the can, and serves to receive up withinl it a tubularstud, d, provided with 011e or more side openings, e, which, when theelastic bottom U is not sprung inward, are out ot' line with theapertures c in the tubular extension b, but so that when the .elasticbottom or diaphragm is sprung inward to compress the air in the can andeject the oil they-that is, the openings e-are brought in line with theapertures c, and egress accordingly established for the oil through thenozzle. These ditl'erent positions of the apertures c and e are clearlyshown in Figs. l. and 2 ot' the drawing. 'Vhen in the positionrepresented in Fig. 1, then the tubular stud d closes the openings c sothat oil cannot escape even though the can be inverted.

Fig. 3 shows a like. construction of nozzle, at least so t'ar as regardsits tubular inward extension b, but of a different form externally andshorter, the invention not being restricted to anyv particular kind orstyle of nozzle.

What is here claimed, and desired to he secured by Letters Patent, is-

The combination, with the elastic bottom and nozzle of the can, of thetubular stud d and tubular sleeve b, arranged and operatingsubstantially as and for the purpose herein described.
